I managed to get obsd installed by underclocking my mobo and sitting thru
all the error messages. They still occur frequently, and occasionally
hang the console forcing reboot.
I have noticed some advice re pciide at:
12.1 - Forcing DMA access for IDE disks
With the PCI IDE code, your chipset may not be known. If so, you will get
a message like:
pciide0: DMA, (unused)
If you get this message, you can try and force DMA mode by using 'flags
0x0001' on your pciide entry in your kernel config file. That would look
something like this:
pciide* at pci ? dev ? function ? flags 0x0001
basically, I would like to try to turn -off- dma, cos I think that is what
is causing the probs.
I have tried to use config to do this, but am unsure how to proceed.
Do I need to have sources, or can I build a config file with just the
using ukc and change seems hard as I do not have the 'flags' option.
::Try to disable UDMA modes:
::boot -c from boot prompt.
::ukc> change wd
:: 12 wd* at wdc0|wdc1|wdc*|pciide* channel -1 drive -1 flags 0x0
::change [n] y
::channel [-1] ?
::drive [-1] ?
::flags  ? 0x0f00
:: 12 wd* changed
:: 12 wd* at wdc0|wdc1|wdc*|pciide* channel -1 drive -1 flags 0xf00
